Embodiment 1
[0072] The present embodiment carries out the preparation of fig extract, comprises the following steps:
[0073] After slicing the fig pulp, weigh 500g of fig pulp and place it in a 5L three-neck bottle, add 3L of 60% ethanol aqueous solution to soak for 24h, heat to 80°C for 2h under mechanical stirring, cool to room temperature, and filter to obtain the mother liquor of fig extract 1. Add 2 L of 40% ethanol aqueous solution to the filtered fig residue, heat to 80° C. for extraction for 2 h under mechanical stirring, cool to room temperature, and filter to obtain fig extract mother liquor 2. Fig extract mother liquor 1 and mother liquor 2 were combined, concentrated under reduced pressure at 50° C. to obtain fig extract.
Embodiment 2
[0075] The present embodiment carries out the preparation of Maillard reaction product, comprises the following steps:
[0076] Accurately weigh 180g of fig extract and 75g of glycine, add 1L of propylene glycol and water mixed solution, add while stirring, dissolve glucose and glycine under room temperature ultrasonic conditions in the mixed solution of propylene glycol and water, cool to room temperature after the dissolution is complete, use Food grade NaOH was used to adjust the pH to 7. Insert the suction pipe of the online synthesis reaction system into the prepared reaction material, adjust the temperature of the constant temperature circulator to 150°C, and when the temperature of the online synthesis reaction system reaches 150°C, adjust the pressure of the online synthesis reaction system to 4bar , the flow rate of the reaction material was adjusted to 6.38mL / min, the reaction termination time was 10min, and the Maillard reaction product was collected at the outlet o...
